Date: Fri, 30 Nov 2007 16:07:06 +0100 From: Jesper Nilsson <jesper.nilsson@...s.com> To: Andrew Morton <akpm@...ux-foundation.org>, Mikael Starvik <mikael.starvik@...s.com>, Jesper Nilsson <jesper.nilsson@...s.com>, linux-kernel@...r.kernel.org, sam@...nborg.org Subject: [PATCH 23/47] Update CRIS main Kbuild makefile. - Remove old and non-generic targets, use generic ones instead. - Add sub-arch as mach-fs or mach-a3 for EtraxFS and Artpec-3 respectively. - Add links to sub-arch directories, and erase before trying to create them. - Include from sub-arch specific include directory "mach". - Add files to be cleaned in CLEAN_FILES instead of as archclean target.
